Plyometric training performance in elite-oriented prepubertal female gymnasts

Area of Science:

• Sports Science
• Biomechanics
• Exercise Physiology

Background:

• Elite gymnasts require exceptional jumping ability.
• Traditional training may not fully optimize explosive power.
• Longitudinal studies are crucial for understanding training adaptations in young athletes.

Purpose of the Study:

• To compare the effectiveness of combined strength and plyometric training versus apparatus-based training on jumping performance.
• To assess training adaptations over two consecutive gymnastics seasons in elite female gymnasts.
• To analyze specific jump performance variables including flight time, contact time, and estimated mechanical power.

Main Methods:

• A 20-month longitudinal study involving nine elite female gymnasts.
• Two training phases (control and experimental) per season, with plyometric drop jumps assessed before and after each phase.
• Measurement of flight time (FT), contact time (CT), flight-contact ratio (FC), and estimated mechanical power (Bosco expression [BE]).

Main Results:

• Combined training (experimental periods) showed larger relative improvements in FT, BE, and FC compared to control periods.
• Flight time (FT) improved during both experimental and control periods.
• Despite training, gymnasts experienced detraining during competitive and transition phases, failing to maintain peak performance.

Conclusions:

• Combined heavy resistance and high-impact plyometric training is effective for enhancing jumping performance in prepubertal gymnasts.
• This training approach yields superior results compared to apparatus-based routines.
• Detraining effects during competitive periods highlight the need for strategic in-season training management.
